A large study – 3,881 women, 2,053 men – by researchers at Trinity College Dublin has determined that people who eat more yogurt tend to have denser hip bones and thus a reduced risk of osteoporosis, a chronic condition leading to weaker bones and more bone fractures. The researchers looked at a wide array of possible risk factors, including BMI, kidney function, physical activity, servings of milk or cheese, calcium or vitamin D supplements, smoking, inactivity, and alcohol use. After adjusting for these, they found that a unit increase in yogurt intake in women was associated with a 39 percent lower risk of osteoporosis, and a 52 percent lower risk in men. Vitamin D supplements also helped reduce osteoporosis risk.
